The H line motors frame size 56-132 are designed to be supplied by inverter.

These motors can ba driven up to the rated frequency (50Hz) with supply voltage proportional to the frequency. At higher frequencies they can be supplied at constant voltage up to the achievement of the maximum speeds expected for each motor.

The H line motors frame size 56÷132 also comply with the following Standards:
